Answer. 18,000 lbs of food.
Explanation. First, let’s find how much food 12 elephants eat in ONE day. Since we already know in one day, one elephant eats 300 lbs, multiply 300 (lbs of food) by 12 (elephants). We now know that in one day, 12 elephants eat 3,600 lbs of food. To find how much they eat in 5 days, simply multiply 3,600 by 5. In 5 days, 12 elephants eat 18,000 lbs of food.
